Grey goo. Grey goo (also spelled gray goo) is a hypothetical end-of-the-world scenario involving molecular nanotechnology in which out-of-control self-replicating robots consume all matter on Earth while building more of themselves,[1][2] a scenario that has been called ecophagy ("eating the environment").[3] The original idea assumed machines were designed to have this capability, while popularizations have assumed that machines might somehow gain this capability by accident. Definition[edit] The term was first used by molecular nanotechnology pioneer Eric Drexler in his book Engines of Creation (1986).
In Chapter 4, Engines Of Abundance, Drexler illustrates both exponential growth and inherent limits (not gray goo) by describing nanomachines that can function only if given special raw materials: Drexler describes gray goo in Chapter 11 of Engines Of Creation: Early assembler-based replicators could beat the most advanced modern organisms.
